One such plant is the lavender tree, which, with proper lavender tree care outdoors, boasts a wide range of benefits and can be used for both ornamental and utilitarian purposes.

But lavender flowers are known to be finicky when it comes to their living conditions. From the type of soil they need to the amount of sunlight they require, there are several things to consider when caring for an outdoor lavender tree.

In this guide, we dive into everything you need to know about lavender tree care outdoors, including tips on how to plant, water, and fertilize your tree. In addition, our lavender tree care instructions will cover common problems that lavender trees face and offer solutions on how to prevent or fix them. By the end, you should have a better understanding of how to properly care for this beautiful and fragrant tree.

Lavender Tree Care Outdoors: The Basics

The lavender tree is a classic addition to any home or garden. But the varieties of lavender (Lavandula angustifolia, Lavandula stoechas, and Lavandula x intermedia) differ in their requirements for sun, water, and soil.

● Lavandula angustifolia (English lavender) is the most popular type of lavender and can tolerate partial sun. It requires well-drained soil and weekly watering.

● Lavandula stoechas (Spanish lavender) prefers full sun and needs well-drained, sandy soil. It is drought-tolerant and only requires watering every two weeks.

● Lavandula x intermedia (French lavender) is a hybrid of English and Spanish lavender. It prefers full sun and needs well-drained, sandy soil. It is also drought-tolerant and only requires watering every two weeks.

Lavender Tree Care Outdoors: The Climate

Lavender grows best in climates that are warm and dry. It can tolerate cold weather but may not bloom as frequently. Therefore, in colder climates, it is best to plant lavender in the spring so that the plants have time to establish themselves before the winter months.

It’s also essential to note that lavender flowers love full sun. As a result, they are traditionally drought-tolerant plants, so they don’t require much water. However, if you live in an area with high humidity, you will need to water your lavender more frequently to prevent root rot.

Lavender Tree Care Outdoors: Planting Your Tree

When to Plant: When planting your outdoor lavender tree, new growth should be visible on the plant. Early spring is the best time to plant lavender, as the plants will have a longer growing season. But you can plant lavender as late as early summer, as long as you give the plants enough time to establish themselves before the winter months.

The Location: When choosing a location for your lavender tree, make sure it is in an area that gets full sun and has good drainage. Lavender does not like wet feet, so make sure your chosen place has good drainage and is not prone to flooding.

The Drainage: You can improve drainage in your planting area by adding organic matter, such as compost, to the soil. If you live in an area with heavy clay soil, you may also want to add sand to the mix.

The Preparation: When preparing the hole for your lavender tree, make sure it is twice as wide as the root ball and just as deep. This will give the roots room to spread out and establish themselves.

Lavender Tree Care Outdoors: Watering Your Tree

Excess water is a danger to lavender plants, as it can lead to root rot. Therefore, it’s crucial to ensure the planting area has good drainage and that you don’t overwater your lavender tree.

Water your lavender tree deeply but infrequently. The best way to water lavender is to soak the roots once a week. This will help the plant develop a deep root system that can better withstand periods of drought.

During the summer months, you may need to water your lavender tree more frequently. If the leaves start to wilt, that is a sign that the plant needs more water. In addition, good air circulation is vital for lavender plants, so make sure to water early in the day so that the leaves have time to dry before nightfall.

Lavender Tree Care Outdoors: Fertilizing Your Tree

Lavender is a light feeder, so it doesn’t require a lot of fertilizer. In fact, too much fertilizer can actually harm the plant.

If you do choose to fertilize your lavender tree, do so in early spring and late summer. Use a balanced, organic fertilizer and apply it according to the package directions. Early fall can also be an excellent time to fertilize lavender, as it will help the plant prepare for winter.

Lavender Tree Care Outdoors: Pruning Your Tree

Pruning is an integral part of lavender tree care. It helps to encourage new growth and keep the plant healthy. This is especially true in herb gardens, where regular pruning is necessary to prevent the lavender from taking over and unleashing its full fragrant potential.

For the best results, prune your lavender tree in early spring and early summer. You can also prune it in late summer, but be sure to do so before the plant starts to bloom. This will ensure that the plant has time to recover before the winter months.

To prune:
1. Cut back the plant by about one-third.
2. Cut back any dead or diseased branches.
3. Shape the plant by trimming back any long or leggy branches.

Lavender Tree Pests and Diseases

lavender tree care outdoor tips

Lavender is generally a very hardy plant, but there are a few pests and diseases that can affect it. These include root rot, powdery mildew, scale, and spider mites.

● Root rot is a fungal disease that can be caused by overwatering or poor drainage. If you suspect your plant has root rot, remove it from the pot and replant it in fresh, well-draining soil.

● Powdery mildew is a white powder that can form on the leaves of lavender plants. It is caused by too much moisture and can be controlled with a fungicide.

● Scale is a tiny insect that feeds on the sap of lavender plants. It can be controlled with an insecticide.

● Spider mites are tiny spider-like creatures that can infest lavender plants. They are most commonly found in dry, dusty conditions. To control them, mist the plant with water and then apply a miticide.

Lavender Tree Red Flags

The type of lavender blooms you see can give you some clues about the health of your plant. Or red flags. This is what to look for:

● If the lavender blooms are small and few in number, this is a sign that the plant is stressed. This can be caused by too much or too little water, poor drainage, or a lack of nutrients.

● If the lavender blooms are yellow or brown, this is a sign of a nutrient deficiency. This can be corrected by fertilizing the plant with a balanced, organic fertilizer.

● If the lavender blooms are black, this is a sign of root rot. This can be caused by overwatering or poor drainage. To correct it, remove the plant from the pot and replant it in fresh, well-draining soil.

● Alkaline soil and clay soil can also cause problems for lavender plants. If the soil is too alkaline or clay, it can stunt the plant’s growth and cause the leaves to turn yellow. To correct this, add some organic matter to the soil to lower the pH.

● Hours of direct sunlight and harsh winters can also cause problems for lavender plants. If the plant is not getting enough sunlight, it will become etiolated, and the leaves will turn yellow. To prevent this, make sure to plant your lavender in a sunny spot.

● In a perennial garden, lavender grows best in well-drained, sandy soils. If your soil is too heavy or clay, you can add some organic matter to loosen it up.

The Best Potting Mix For An Outdoor Lavender Tree

The potting mix you use for your lavender tree can make a big difference in its health and growth. As you may have noticed, lavender plants prefer well-drained soils. This means that the potting mix you use should be light and airy.

A good potting mix for lavender includes:
● Perlite
● Vermiculite
● Coconut coir
● Sand

If you can’t find a potting mix that contains all of these ingredients, you can mix them yourself. Just make sure the ratio of perlite to vermiculite is about 3:1.

The size of the pot you use for your lavender tree is also important. Lavender plants prefer smaller pots so that they don’t become rootbound. On the other hand, if the pot is too large, the plant will have difficulty getting the nutrients it needs. In general, a pot that is 12-18 inches in diameter is a good size for an outdoor lavender tree.

Plastic pots, terracotta pots, and clay pots are all excellent choices for lavender trees. Just make sure the pot has drainage holes in the bottom so that the plant doesn’t become overwatered.

Lavender Tree Winter Care

If you live in a colder climate, you will need to take some extra steps to protect your lavender tree during the winter months. This means covering the plant with a layer of mulch or burlap.

Mulching will help to insulate the roots and prevent them from freezing. Burlap can also be used, but make sure to remove it in the spring so that the plant can get the sunlight it needs.

In addition, you may want to consider moving your young plants indoors during the winter months. This will help to protect them from the cold and allow them to continue growing throughout the year.

The Conclusion

Lavender trees are beautiful and fragrant additions to any home, but these purple flowers don’t come without some special care. From the type of lavender you choose to the size of the pot, the best way to care for an outdoor lavender tree is to be informed about the plant’s needs. With a little bit of knowledge, you can ensure that your lavender tree will thrive for years to come.
